Schistura Waltoni
''Schistura waltoni'' is a species of ray-finned fish, a stone loach, in the genus ''Schistura''. It is a species of in streams which have a moderate to fast current where it can be found in riffles, over gravel to rock beds. It is often recorded in small streams in forest, even where the water is very shallow. It occurs in the upper reaches the Chao Phraya watershed in Thailand in the rivers Mae Nam Ping, Mae Nam Wang and Mae Nam Yom. The specific name honours Joseph Walton a 19th Century contributor to the fish collection at the Academy of Natural Sciences of Philadelphia The Academy of Natural Sciences of Drexel University, formerly the Academy of Natural Sciences of Philadelphia, is the oldest natural science research institution and museum in the Americas.

Henry Weed Fowler
Henry Weed Fowler (March 23, 1878 – June 21, 1965) was an American zoologist born in Holmesburg, Philadelphia, Holmesburg, Pennsylvania. He studied at Stanford University under David Starr Jordan. He joined the Academy of Natural Sciences in Philadelphia and worked as an assistant from 1903 to 1922, associate curator of vertebrates from 1922 to 1934, curator of fish and reptiles from 1934 to 1940 and curator of fish from 1940 to 1965. He published material on numerous topics including crustaceans, birds, reptiles and amphibians, but his most important work was on fish. In 1927 he co-founded the American Society of Ichthyologists and Herpetologists and acted as treasurer until the end of 1927. In 1934, he went to Cuba, alongside Charles Cadwalader (president of the Academy of Natural Sciences of Drexel University, Academy of Natural Sciences of Philadelphia), at the invitation of Ernest Hemingway to study billfishes, he stayed with Hemingway for six weeks and the three men devel ...

Hugh McCormick Smith
Hugh McCormick Smith, also H. M. Smith (November 21, 1865 – September 28, 1941) was an American ichthyologist and administrator in the United States Bureau of Fisheries. Biography Smith was born in Washington, D.C. In 1888, he received a Doctor of Medicine from Georgetown University; then, in 1908, a Doctor of Law from the Dickinson School of Law at Dickinson College. He began working for the United States Fish Commission (formally, the United States Commission on Fish and Fisheries) in 1886 as an assistant. He directed the scientific research center there from 1897 to 1903. From 1901 to 1902, he directed the Marine Biological Laboratory at Woods Hole, Massachusetts.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Chao Phraya
The Chao Phraya River is the major river in Thailand, with its low alluvial plain forming the centre of the country. It flows through Bangkok and then into the Gulf of Thailand. Etymology Written evidence of the river being referred to by the name ''Chao Phraya'' dates only to the reign of King Mongkut (Rama IV, 1850–1868). It is unknown what name, if any at all, was used for the river in older times. The river was likely known simply by the Thai word for 'river', (), and foreign documents and maps, especially by Europeans visiting during the Ayutthaya period, usually named the river the ''Menam''. The name Chao Phraya likely comes from (), an alternative name, documented from around 1660 in the reign of King Narai, of the settlement that is now Samut Prakan. Historian Praphat Chuvichean suggests that the name, which is a title of nobility, originated from the story of two Khmer idols being unearthed in 1498 at the settlement that was by the mouth of the river at the tim ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Academy Of Natural Sciences Of Philadelphia
The Academy of Natural Sciences of Drexel University, formerly the Academy of Natural Sciences of Philadelphia, is the oldest natural science research institution and museum in the Americas. It was founded in 1812, by many of the leading naturalists of the young American republic with an expressed mission of "the encouragement and cultivation of the sciences". It has sponsored expeditions, conducted original environmental and systematics research, and amassed natural history collections containing more than 17 million specimens. The Academy also organizes public exhibits and educational programs for both schools and the general public. History During the first decades of the United States, Philadelphia was the cultural capital and one of the country's commercial centers. Two of the city's institutions, the Library Company and the American Philosophical Society, were centers of enlightened thought and scientific inquiry.
